This work investigates the carbonation of hydrated oil-well cements by reactive transport modelling. The study focuses on changes in the cement phase assemblage due to CO2 exposure under saturated conditions. The predictions of a reactive transport model were subsequently tested against experimental work, namely microstructural investigations paired with mineralogical characterization. The intention of this work was to identify different assumptions in the modelling approach on kinetic parameters that control the carbonation processes. This aspect is of high importance for the estimation of the CO2 uptake in oil-well cements and improves the understanding of the simultaneous microstructural changes.
